Abstract: A passive-motion having a support surface provided by a plurality of bellows-like or bladder-like cells which are sequentially or independently inflatable and deflatable to alter the configuration of the support surface continuously to cause a person seated on the support surface to continuously and instinctively adjust the additude of his spinal column and associated muscles.

Abstract: An improved folder includes a "soft stop" reversible roll nip. Folding is accomplished by feeding a copy sheet into a stepper/servo controlled pinch roll that is under software control. The copy sheet is measured and the reversible roll nip is cycled from full forward to full reverse velocity with controlled acceleration. The reversing of the sheet causes a buckle to be created and the sheet creased by a secondary set of rolls.

Abstract: Telephone use control apparatus in which a microcontroller controls the functions of the apparatus and in which the apparatus is provided with batteries to maintain power to the microcontroller and circuitry associated therewith when the the telephone is in operation, and means for providing power from the incoming telephone line to run the apparatus when the telephone is not in use. The incoming power from the telephone line is also usable to recharge the batteries. In addition, the case for the apparatus is made to mount the electrical components without the use of screws, and to permit the assembly of the various parts of the case, also without screws.

Abstract: A movable heavy duty voting booth with a structural frame and lightweight panels to accommodate electronic voting mechanisms.

Abstract: An electrostatographic type copying or reproduction machine incorporating a programmable controller to operate the various machine components in an integrated manner to produce copies. The controller carries a master program bearing machine operating parameters from which an operating program for the specific copy run desired is formed and used to operate the machine components to produce the copies programmed. A multiple prioritized interrupt system is employed to distribute the operating program to the machine.

Abstract: A xerographic type copying or reproduction machine incorporating a programmable controller to operate the various machine components in an integrated manner to produce copies is disclosed. The controller carries a master program bearing machine operating parameters from which an operating program for the specific copy run desired is formed and used to operate the machine components to produce the copies programmed. A fault flag array is routinely scanned, each flag comprising the array being associated with an operating component or area of such machine such that on a fault or malfunction thereof, the fault flag corresponding thereto is set. On detection of a fault flag, a machine fault is declared. Display means are provided to visually identify the fault location. A permanent record of certain faults and machine operations are stored in memory for future use.
